REFLECTOR.

Specification of letters Patent. Patented Nov. 14, 1911.

' Application filed May 17, 1910. Serial No. 561,848.

To all whom it may concern:

Be it known that I, WILLIAM HAEHNEL, a citizen of the United States of America, and a resident of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Reflectors, of which the following is a specification.

, The object of this invention is to produce a reflector which is,.particularly suited for use in connection with lamps where it" will be subjected to high temperatures and to extreme and rapid changes of temperature.

A further object of the invention is to produce a reflector which is .not easily roken either by being subjected to inequalities of temperature or to mechanical shock, and in which, owing to the refractory character of the support for the reflecting elements, high temperatures may be employed in their preparation.

In the accompanying sheet of drawings which forms a part of this application Figure 1 is a face view of a reflector embodying my invention. Fig. 2 is a section on the line IIII of Fig. 1.

An opaque refractory base of earthenware E with a White opaque vitreous glazed surface G, which in the form shown is of an even concave to form a reflector suitable for an automobile lamp, carries a thin silver deposit S, and on top of .the silver. deposit a thin protecting polished deposit of a nontarnishing metal, as platinum P. Both metals. may be applied in liquid form and converted to pure metallic condition by heat. The deposits are extremely thin so that their elastic tension Will not overcome the adhesion to the support and result in their becoming detached through unequal expansion. This for successful results requires a thinness which on a transparent support would yield a poor reflection and'be' practically transparent. But, I find that upon a white opaque support a deposit of such thinness becomes suitably reflecting.

' What I claim as new, and desire to secure by Letters Patent of the United States, is

1. A reflector consisting of an earthen ware body with a glazed face bearing a polished metallic deposit which is so thin that by itself it would be transparent.

2. A reflector consisting of an "earthen Ware body with a silver deposit which 1s so thin that'by itself lazed face bearing a,

it would be transparent, and a transparent polished protecting deposit of a non-tarnishing metal.

3. A reflector consisting of an earthenware body with a glazed face bearing a silver deposit which is so thin that by itself it would be transparent, and a transparent polished protecting platinum deposit.

4. A reflector consisting of a white earthenware body with a glazed face bearing a polished metallic deposit which is so thin that by itself it would be transparent.

Signed by me at New York, N Y., this 16th day of May, 1910.

WILLIAM HAEHNEL.
